oil cooler line

[Joan Kotjarapoglus <jkot+@pitt.edu>]

Recently, I relayed a concern with the remaining life on the oil line
going from the turbo to the oil cooler. My 87tq has 166K and feedback was
yes it time for a replacement.  So, I scheduled it in for my local
mechanic to take it off, preserve the fittings if possible and have a
local shop replace the hose portion.  Well, Wednesday was the day, but on
Monday, it blew the hose off the crimp fitting so I ended up towing it to
the garage 2 days early. Steel nut was bonded to the aluminum cooler, so a
grinder disk used to remove it. My mechanic, Dave Campos, is exceptionally
bright and able so he used a air conditioning fitting to replace the
origional rusted piece - spread the end - and  used the hose for it still
seemed fine, then used 2 clamps.  The first is tighended moderately on the
spead end to have the fitting bite into the hose, and the second at the
end of the hose is super tight.  The top hose fitting was not rusted so he
left it alone.  Has anyone had the hose itself go on either the top or
bottom.  Ordinarily, it is the crimp fitting that rusts and then the hose
blows of the end.
